Abstract

This work studies the influence of operating factors on the microfiltration of baker's yeast (Saccharomyces cerevisiae) in presence of static mixer as turbulence promoter. Microfiltration is typically used to remove particles in range 0.1-10 pm from a suspension. It is a pressure-driven process widely used in concentrating, purifying or separating suspended particles and macromolecules from solution. During cross-flow microfiltration process permeate flux decreases with time as the retained particles are accumulated on and within membrane surface area where they create additional resistance to permeate flow. External fouling of the membrane is the result of cell, cell fragments and rejected particles accumulation on the top of the membrane surface in the course of cake formation, while deposition of the macromolecules and small particles inside of the internal porous membrane structure results in internal fouling, which is often irreversible contrary to usually reversible external fouling. Experimental work was done with three membranes (A, B and C) with pore size 200, 450 and 800 nm. The results of microfiltration experiments for each membrane were estimated by analyzing the permeate flux without static mixer; permeate flux with static mixer; permeate flux improvement; reduction of specific energy consumption. Experimental results suggest that even though membrane A has smallest pore size of 200 nm it has the best performance considering steady state flux and reduction of specific energy consumption.
